Developer faces $36,000 Cloudflare bill due to AI agent memory service bug

A developer reportedly incurred a $36,000 Cloudflare bill in one month for a small AI agent memory service with only 81 users. The issue stemmed from bugs that caused the system to repeatedly execute the same work, leading to excessive usage charges on Cloudflare Workers, KV, Durable Objects, and Queues. The incident highlights the financial risks associated with pay-per-use cloud services for AI applications when bugs cause infinite loops.
